Answer this question truthfully
### Question: Who is at highest risk for Pterygium ?
### Response: Pterygia are more common in people in the 20-40 age group that live in sunny, dry climates. Additionally, chronic dry eye is believed to contribute to pterygium. Risk factors are exposure to sunny, dusty, sandy, or windblown areas. As a result, farmers, fishermen, and people living near the equator are often affected. While some studies report a higher prevalence of pterygia in men than in women, this may reflect different rates of exposure to UV light. Pterygium is rarely observed in children.
